US/Europe

The SCON-KIT would be very difficult to get in the US/Europe. You would likely have to use a different Serial Converter

The serial port signals from the processor are only 3.3V. For proper RS-232 12V signaling, an RS-232 level shifter needs to be added. These are very common in PDA serial cables also, but can be purchased

Models other than KuroPro

If you are attaching a serial header pin onto the main board, you may want to consider:

Using the header pin unit with a 90 degree bend, or you might not be able to close the case

Soldering it with the pins toward the interior, rather than toward the case. This allows easier access, since if the pins face the case side they would be very close to the metal side. This would make access is so tight that one might end up taking the board out to get plug fitted on the pins.

Solder the 4-pin header to the board. Make sure you don't have shorts.

You will need to switch wires on the TTL-232R-3V3 cable. Use a sharp object to lift the plastic tabs and carefully pull the wires out. Rearrange them according to the table above (black, empty, orange, yellow, empty, empty) and slide those wires back in. Tape the other wires to make sure they don't short anything.

When plugging in the cable, make sure black aligns with GND, yellow with TXD, and orange with RXD.

Connect the USB cable to your computer, start a terminal program with the right settings.

Turn on the device, you should see output from the bootloader in couple seconds.

Attach a Serial Header to the Daughterboard

Do not insert/extract or push/pull attached connector frequently

Do not put stress on connector and base

Do not attach connector when the power of KURO-BOX/PRO is on

You will need terminal software

Attach Serial Header to circuit board by soldering iron make sure the AC plug is off.

Open front panel of KURO-BOX/PRO, take the HDD daughter board out.

Put the serial header onto UART0.

Make sure that pin No.1 matches to TXD.

Attach with a soldering iron from the back of the base.

Put the daughterboard back onto the KURO-BOX/PRO

Use the SCON-KIT as a USB/TTL converter

Connection of SCON-KIT/PRO

Connect SCON-KIT/PRO and UART0 on the sub base of KURO-BOX/PRO by using a patch cord

Do not connect to the PC yet.
